On　the　basis　of　the　annular　fuel　for　PWR,　a　new　type　annular　fuel　for　SCWR　has　been　designed　in　this　paper,　which　has　bigger　size　than　that　of　PWRs,　adopts　UO2　particles　instead　of　fuel　pellets　and　coats　heat-barrier　material　on　the　surface　of　the　inner　cladding.　Then　a　new　1000MWe　SCWR　design　concept　CSR1000A　has　been　developed,　whose　core　consists　of　163　hexagonal　fuel　assemblies　that　are　made　up　with　61　new　annular　fuels　and　assembly　box.　After　CSR1000A　core　evaluation,　these　core　key　parameters　such　as　discharge　burnup,　coolant　averaged　outlet　temperature　and　maximum　fuel　cladding　temperature　are　presented.
